he JG of mechanical processing is coordinate grinding.
JiaGong=JG= processing. JG is a coordinate and high precision machine tool. It is mainly used to process inner holes with an accuracy of 0.002 mm. NC coordinate grinding can also process contours. CBN grinding wheel (cubic boron nitride) and diamond grinding wheel are commonly used to grind cemented carbide materials.
Coordinate grinder is a machine tool developed for eliminating heat treatment deformation of materials. It can grind holes with high accuracy and various contour shapes. The machine is equipped with precise coordinate mechanism, and the moving parts of grinding wheel rack and worktable are equipped with data devices, which can show the magnitude of its movement.
The coordinate grinder has a precise coordinate positioning device, which is used to grind precise holes and forming surfaces with high accuracy requirements. The coordinate grinder and the coordinate boring machine have the same structure layout, but the main axis of the boring cutter is replaced by the high-speed grinding head. In grinding, the workpiece is fixed on the worktable which can move according to coordinates. In addition to high speed rotation, the grinding wheel also rotates slowly through planetary transmission mechanism and can move vertically. In addition to grinding cylindrical holes, coordinate grinders can also grind the inner and outer surfaces of arcs and conical holes. They are mainly used for processing hardened workpieces, punching dies and pressing dies. Installing insert grinding accessories on the grinding head can make the axis of the grinding wheel in horizontal position. The grinding wheel does not move planetary, but only moves up and down. It can be grinded in the form of insert grinding to process inner gear ring, indexing plate and cam, etc.
